Cisco Updated 200-301 Exam Questions and Answers by omari

This drag-and-drop question tests whether the protocol normally uses TCP or UDP as its transport service. TCP is selected when the application requires connection setup, acknowledgments, sequencing, and retransmission. Protocols such as HTTP, HTTPS, FTP, SSH, Telnet, and SMTP commonly rely on TCP because reliable delivery matters more than minimal overhead. UDP is selected when the application benefits from low overhead, simple request/response behavior, or real-time delivery where late retransmission is not useful. DNS queries, DHCP, TFTP, SNMP polling, NTP, voice media, and many streaming functions commonly use UDP. Some protocols can use both in special cases, but CCNA questions normally expect the standard default transport. Cisco CCNA v1.1 Network Fundamentals includes application protocols and transport-layer behavior. The correct mapping should therefore follow function: reliable session-based applications go to TCP, while lightweight discovery, timing, addressing, and real-time-style exchanges usually go to UDP.

Use D for this item. A switch builds its MAC address table from ingress traffic. When a frame enters a port, the switch records the source MAC address and the receiving interface in the table. In Cisco CCNA 200-301 v1.1, Network Access questions frequently test the practical boundary between similar features: what the feature does, where it is configured, and what problem it is meant to solve. DTP and VTP serve trunk negotiation and VLAN database functions, and egress traffic is not how the switch learns the source location. A clean way to validate the answer is to map the wording of the scenario to the actual device function. If the feature supplies addressing, forwarding, authentication, trunking, route selection, or controller communication, the answer must match that function exactly rather than a nearby protocol name.

When two routing protocols advertise a route to the same destination, the router first compares administrative distance. Administrative distance is Cisco IOS’s trust value for the source of routing information. A lower AD is preferred over a higher AD, so an EIGRP internal route with AD 90 is preferred over an OSPF route with AD 110, and both are preferred over a RIP route with AD 120. Metrics are compared only among routes learned from the same routing protocol, not across different protocols. Hop count is a specific metric used by RIP, and DUAL is the algorithm used by EIGRP, not the cross-protocol decision mechanism. This is a core CCNA 200-301 v1.1 IP Connectivity rule: longest prefix match chooses the most specific route first, and administrative distance decides between different routing information sources for the same prefix. Therefore the verified answer is C. Reference: Cisco IOS route selection and administrative distance behavior.

The verified answer is D. service password-encryption encrypts supported plaintext passwords in the running configuration. It provides basic obfuscation for line passwords and other password fields so casual viewers do not see clear text. Cisco CCNA 200-301 v1.1 places this skill in Security Fundamentals, where the exam expects a working understanding of how the feature behaves on real Cisco networks, not just a memorized command. enable secret protects only the enable secret value, while the other listed commands are not the correct IOS global command. In production, this distinction matters because a misapplied command or design choice usually creates an outage, a security gap, or unnecessary troubleshooting noise. The correct choice matches the control-plane, data-plane, wireless, security, or services behaviour described in the scenario and should be preferred over options that merely sound related.
